I "be made with a single inking of'the device and with ease and dispatch, the device being so constructed that wrinkling of the sheet being imprinted as well, as wrinkling of thestencil sheet will be prevented, the stencil sheet being readily removable from the de I vice to permit'r'einking of the latter when necessary. I y V The device preferably embodies a cylini der rotatably mounted" on an axle serving as a handle by which the cylinder can be manuallyfrolled over the surface of a sheet to be imprinted, the cylinder being counterbal- 'an'ced' in such manner'that when; lifted it will be urgedi'to rotate upon the axle to position in which th'e'end portions of its stencil sheet will be disposed downmost and I thus properlyposition the stencil sheet for aprintingoperation', the cylinder also be ng formed in a manner to permit it tobeplaced upon a table or other flat, support'fand left without danger of itsrolling.

The device -may or may not be used with a platen'o'n which 'canbe placed the sheetto be imprinted and whichis provided with Y II means co-operating with the cylinder in such T manner that its 1 rolling movement on the platenjcan be initiated from a predetermined I point along the length of and transverselyof theplaten; j I K a I will describe only one form ,of stencil' duplicating device embodying my invention, andwill' then point-out" the novel features thereofin'claims.

within the opposite ends of which is secured, .by soldering or other suitable means, end walls 11 of disk form. The end walls are recessed; or cut away at the longitudinal I edges of the wall 10, as indicated at 12, and

for the purposeof stiffening the longitudinal edges, members in the form-of relatively large rods 13, extend along the edges and are soldered to the inner side of the-wall 10.

The cylinder C is. rotatably mounted upon I an axle 14 formed of a pair of rod sections projecting through axial openings in theend walls 11 and vconnected together by .means of a threaded sleeve 15. The cylinder 1 is adapted to be manually lifted orrolled over the surface of a sheet to beimprinted by means of handles 16 securedto the opposite ends of theaxle by pins 17 I The cylinder serves as a support for stenciling and inking means and in the. present instance .I provide a backing or-pad 18 therefor which is formed of heavy cloth of a double thickness wrapped around the wall 1 0 and having its ends looped to. receive rods 19 and trained over the members 13 within the endwallslll The inking means,

preferably comprising a sheet of paper or cloth 20 to which is adapted to be applied a suitable duplicating ink, is; next wrapped over the pad .18 or if desired a sheet of mate rial21 impervious to ink, such, for instance, as metal foil or paper treated with shellac, may first be interposed between the pad and provide a solid wall 10 ofsegmental form inking sheet to prevent contamination of the I formerby the ink of the latter. The ends ofthe inking sheet 20 are trained over the members 13 and looped to receive rods 22 which extend through openings formed in the endwalls l1 and project beyond theoutersidesof the walls a short distance for a purposeto be hereinafter;described. I

The stenciling means preferably comprising a sheet of suitably waxed paper 23 upon which hasbeenheavily typewritten or otherwise impressed the matter to be dupli catedis next wrapped around the. wall 10 and for yieldingly supporting the sheet under tension uponthe wall I preferably employ at each end of the cylinder an elastic rubber band 2.4: trainedvover a hook. 25 securedfupon the'outer'side of the end .wall 11 and over the projectingends of headed rods 26 extending through'lo'oped strips'of paper 27, to whichthe extreme endsof the stencil sheet are glued or otherwise secured.

removed from the cylinder C when a reinking of the sheet 20 is necessary, and-that by placing the stencil sheet yielcli'ngly under tension the formation of slack in the sheet with a consequent wrinkling thereof at the point immediately in advance of the contact point of the cylinder with the surface oi the sheet being imprinted ispositively preventecl. .ln additioiu wrinkling of the sheet being impr nted, is also prevented by the p I the platen when such accuracy is-not desired provision ot' the pad 18' which is adapted .toyield su'iiiciently during; the printing op- ;era'tion' to. conform to the irregularities in thickness of the sheet and to slight irreg- "uhiritiesof the sruiace of the support upon which the sheet s placed, thus resulting 1n a perfect copy.

It will be noted that by the provision of the; segmental wall 10 and recessed ends 11 ithe cylinder C'is formed with a flat'side, and that its) weight is counterbalanced by the'weight of the rods 13, 19, 22 and 26 so that when elevated the handles 16 and held insubstantially horizontal position it will be cause'dto rotate upon its axle to a position in which its flat side is presented downinost, thus disposing the. end portions of the stencil sheet 'downinost and in proper starting positionfor a rolling movement of thek'jylinder over the sheet to he imprinted.

The fiat side of the cylinder. serves as a means by which thecvlinderican be rested upon a support and ilett" witl oi1tdanger of its rolling away.

In operation the stops 28' are first secured to the j platen at the desired location with 7 re- "sp'ectto the t'pin s '29 and a sheet of paper to he imprinte l the stops.
